and for other purposes if desired.

The principal objects of the invention are to improve and simplify the construction of brick machines as well as to increase their efliciency in use and to decrease the expense attending their manufacture and operation.

A further object of the invention is to provide a brick machine having improved means for forming a plurality of mold compartments above a common pallet and for easily and quickly removing the walls of said mold compartments from said pallet after the bricks have been molded.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of in-' vention herein disclosed can be made within the scope of the claim without departing from the spirit of the invention.

In the accompanying drawing-s forming part of this specificatiomFigure 1 isa vertical section on the line 1-1 of Fig. 3. Fig. 2 is a front elevation of the machine, partly broken away. Fig. 3 isa plan view of the machine. Fig. 4 is a detail section on the line 4l4t of Fig. 1, taken at one side of the machine.

Like reference numerals indicate corresponding parts in the different figures of the drawings. a

The brick machine of the. present invention is constructed with a suitable frame which preferably includes pairs of supporting legs 11 and 22. The legs of each pair are connected by a cross piece 3. Extending from the cross piece 3 on one side of the machine to the cross piece 3 on the other side of the machine is a connecting member 4: to which is secured by means of a bolt '5 the lower end 6 of a pair of diagonally extending brace rods 7 and 8 which are secured at their upper ends in any suitable manner to the upper ends of the legs 1 and 2. Bolted or otherwise suitably secured at 9 to the upper ends of the legs land 2 is a pair of angle iron sills 10; The angle irons 10, as shown best in F ig. 1, extend some distance re'arwardly of the machine so as to produce an overhanging portion. At their rear ends, the angle irons 10 serve to support a transversely extending angle iron cross bar 11 which isheld in position upon the angle irons 10 by adjusting members such as the bolts 12 each provided with a lower spacin nut 13 and an upper spacing nut 1a, a third nut 15 being disposed below the upper flange of the angle irons 10 to hold the transverse angle iron 11 properly in position upon the angleirons 10.

Supported upon'the forward ends of the angle irons lO-and extending transversely of the machine is a table 16. The table 16 is intended to support a transversely extending pallet or board 17 having a metal plate 18 secured on the upper surface thereof.

Extending along the front edge of the pallet .the forward end of one of the mold com partments as shown in Fig.3. The end gates 20 are secured on the swinging member 19 by means such asthe plates 21 and the bolts 22 and 23, the bolts 22 extending through the plates 21 and gates 20 and the bolts 23 extending through the plates 21 and swinging member 19. The different gate 100 members 20 are separated fromeach other by distances sufficient to permit the sliding side walls 24 of the mold compartments, as

shown in Figs. 2 and 3, to slidetherebetween.

lVhen the side walls 24: of the mold com 105 partments are slid forward from the dotted line position so that they project at their for-ward ends between the gates 20, the, mold compartments are closed and are adapted to receive the cement which is to be molded, 110

. and afterthearticleshave been molded, the

sidewalls 24 are slid backward to the dotted line positionin 'Fig.3*and the front gates 20 are swung opento the'dotted line position in Fig. 3 so as to permit the pallet .17

The cross piece 27 thus serves to hold both the table 16 and the fixed f end walls 26- securely in position. The different fixed walls 26 are spaced away from each" other sufficiently to permit the side lwalls'24 of'the mold compartments to slide therebetween. The fixed end gates 26 of the different mold compartmentsare braced at their upper ends by a transversely extend hingjcross piece 29 which is provided with a plurality of downwardly extending bolts 30 eachi connecting with the upper end of one f "of the end'gates 26 so as to brace the same.

walls 24 and is bolted to said walls so as to be lni'ovable therewith, Between each pair o f walls24, the cross piece 37 has secured {theretobymeans such as the bolts38 a short ,pahgle iron 39 one of which is shown in Fig' 50.

walls 24 and spaces them properly apart. The means for securing the cross piece 37 toithe-sliding'lwalls 24 is best shown in Fig.

.4Land ;consists[ of one or more bolts 40 se-. cured attheir lower ends to cross pieces 41- j-which fit against the lower edges of twoor 1 more of the slidingwalls 24. By tightening.

j the bolts'40 the, cross piece37 is drawn i -24and the cross pieces 41 are drawn tightly I tightly againstxthe 'upperedges of the walls against the lower edges thereof.

For the p-urpose of guiding the sliding walls v24 in their backward and forward movement,,-eaeh of the two outer walls 24 as as shown in Fig. 1, are closed by fixedwalls f 26 wh ch rest at their lower ends upon the movement of the walls 24.

I 1.5; Each of the; angle irons 39 projects downwardly between a pair of the sliding shown in Fig. 4 hasbolted thereto a longitudinally extending strip or rib 42 held in place by the bolt or rivet 43. The-strips 42 are engaged by horizontally disposed plates or guides 44 shown in Figs. 3 and 4. The

plates 44 are secured at their rear ends by means of the bolts 12 tothe rear angle iron 11, suitable spacing members 45 being interposed between the upper fiange of the angle iron 11 and the plates 44 as shown in Fig. 4.

The strips 42 slide beneath the platesv 44 during the forward andbackward sliding The means for sliding the walls 24 into c and out of position preferably ronsi'sts of an operating handle 47 securedon' a-rock shaft 48 which is journaled in the frame work of the machine. The rock shaft 48 is provided with a pair of upwardly extending arms 49 each of which extends between a pair of studs 50 mounted' in one of the sliding walls 24. is thrown forward, the arms 49' simultaneously slide allof' the walls 24 forward; and

when the lever '47 is thrown frearwardly the When the handle lever 47 v walls 24 are simultaneously thrown rear wardly to the dotted lineposition' indicated in Figs. 1 and 3 o-fthe drawings. I

It will be observed from Fig. 1 that the rear stud 50 is disposed in alower horizontal plane. than the forward stud 50, whereby to permitthe rocking frame 41 to be swung to its rearmostposition without binding.

The machine preferably is used as follows. Whilethe Walls 24 are drawn rear; wardly 1nto open position as indicated by the dotted lines in Fig. 3 and the wall 19 is opened aswide as idesiredythe pallet 17 is inserted in'position with its rear edge abutting againstthe fixed walls 26 which form the rear ends of the mold compartments.

The swinging member 19 carrying the front walls orgates 20 of the inold compartments, is then swung 111 closed position, being locked in such position by means of any suitable form of catch such for "example as the springcatch 52 indicated in Fig. 1 of the drawings, .said catch being secured to the bottomof the tablej16 and having an upward pro ection adapted to pass through the,

table and into a socketin the'lower'end of the swinging member '19, said catch being operated by means of a knob or'handle 53. After the front gates 20 are closed, the handle 47 is operated to draw the side members;

24 forward, these members sliding between i .walls 24 into the dotted .linepositionl The swinging member 19 is then unlocked and swung into open position, after which the pallet 17 on which the diflerent molded articles are standing, can be removed from the machine and a new pallet substituted so as to permit the molding operation to be re peated in the manner described.

What is claimed is:

In a brick making machine, a frame; sills mounted on the frame; a table mounted on the sills; a pallet supported on the table; a gate bar pivoted to the table and resting on the same for horizontal swinging movement to aline the upper edge of the gate bar with the upper face of thepallet; a set of spaced end walls secured to the gate bar; a set of fixed, spaced end walls cooperating with the pallet; connected inner and outer side walls mounted to slide across the pallet and across the gate bar between the walls of the respective sets; ribs secured to the outer side walls; guides overhanging the ribs; a cross bar disposed above the sills and constituting a support for the slidable side walls; and adjusting members connected with the sills and with the cross bar to elfect a raising and lowering of the cross bar thereby to level the slidable side walls with respect to the pallet and the gate bar, the guides being retained by the adjusting members.

In testimony that I claim the foregoing as my own, I have hereto aflixed my signature in the presence of two witnesses.
